INSIDE BOTTLE BRUSH George L. N. Meyer, Milwaukee, Wi s., assignor v toGeo. J. Meyer Manufacturing Company, Cudahy, Wis., a. corporation ofWisconsin Application May 4, 1945, Serial No. 591,884

4 Claims. (Cl. 15-206) This invention relates to bottle brushes and moreparticularly to an inside bottle brush for use on bottle washingmachines.

Brushes used in bottle washing machines to clean the inside of thebottles are commonly made by bending a piece of wire in half andtwisting the two ends together with the bristles between the wiresforming a cylindrical brush having a wire loop at one end and jaggedwire edges at the other end. The end bristles are then bent upward andtied to form a brush for the bottom of the bottles.

Such a construction has the disadvantage of leaving rough jagged ends ofthe wire upward toward the bottom of the inverted bottle, causingmarring of the glass as the brush is rotated.

An attempt to remedy this condition was made in the United States patentto George L. N. Meyer, No. 2,272,419, granted February 10, 1942, inwhich a rubber sleeve was inserted over the ends of the wires beforetying the bristles over the end of the brush. This construction, whileprotecting the glass for a time. had the disadvantages of beingexpensive and of wearing out quickly.

One object of the present invention is to provide an inside bottle brushwhich will prevent scratching more effectively.

Another object is to reduce the cost of inside bottle brushes.

A further object is to increase the life of inside bottle brushes.

A still further object is to simplify the construction of inside bottlebrushes.

Other objects will become apparent upon considering the followingspecification which, when taken in conjunction with the accompanyingdrawings, illustrates a preferred form of the invention.

According to the present invention a brush is formed by twisting a pairof wires with bristles mounted between the wires to form a substantiallycylindrical brush, securing the free ends of one end of the wirestogether by applying a coat of solder sufficiently thick to preventsharp edges of the wire from scracthing or marring the bottles.

In the drawings:

Fig. 1 is a view partly in cross-section of a brush embodying thepresent invention;

Fig. 2 is a detail view of the upper end of the brush stock; and

Fig. 3 is a cross-section on the line 3-3 of Fig. 2. I

The brush is made by bending a wire in half forming a loop l0, mountingbristles [2 between the two wires and twisting the wires together asshown at [4 to grip the bristles therebetween and form a substantiallycylindrical brush.

The cut ends of the wire are then dipped in solder or other soft metalwhich binds them together as shown at I6. The solder is applied to asufficient thickness to form a permanent, protective coat and preventthe sharp edges of the wires from scratching the glass. The solder tip16 of the brush thus both binds the ends of the brush stock together andprevents it from unraveling and from scratching the bottles.

The upper portion of the brush has the bristles bent upwardy as shown at8 and bound in place by a wire 20 to form a brushing surface for thebottom of the bottles.

The brush is mounted in the end of a hollow tube 22 by means of a pin 24so that rotation and reciprocating motion are transmitted from the tubeto the brush. 7

Having thus described the invention, it is realized that it issusceptible to various changes and modifications and that such changesin shape, size and arrangement of parts may be made as fall within thescope of the appended claims.

That which is claimed as new and is desired to be secured by LettersPatent is:

1. A bottle brush of the character described, comprising a plurality ofbristles, a pair of wires twisted together to secure the bristlestherebetween and form a substantially cylindrical brush, and a tip onsaid wires of soft metal forming a binder for said wires and aprotection against the ends of the wire scratching the brushed object.

2. A bottle brush of the character described, comprising a plurality ofbristles, a pair of wires twisted together to secure the bristlestherebetween and form a substantially cylindrical brush, and a soldertip on said wires forming a binder for said wires and a protectionagainst the ends of the wires scratching the brushed object.

3. A bottle brush of the character described, comprising a plurailty ofbristles, a pair of wires twisted together to secure the bristlestherebetween and form a substantially cylindrical brush, a tip on saidwires of soft metal forming a binder for said wires and a protectionagainst the ends of the wires scratching the brushed surface and meansto bind a portion of said bristles into an axial position to projectaxially beyond the soft metal tip on the end of said wires.
